<p> This creates an ASF file containing an WMV video stream
with a test picture and WMA audio stream of a test sound.</p>

<div class="refsect3">
<a name="id-1.2.8.8.5"></a><h4>Live streaming</h4>
<p>asfmux and rtpasfpay are capable of generating a live asf stream.
asfmux has to set its 'streamable' property to true, because in this
mode it won't try to seek back to the start of the file to replace
some fields that couldn't be known at the file start. In this mode,
it won't also send indexes at the end of the data packets (the actual
media content)
the following pipelines are an example of this usage.
